page:[うんちく]

はじめに

環境

  • Windows11
  • WSL2のUbuntu
  • IPython

状況

import cv2
import cv2
   ...:
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
Cell In[3], line 1
----> 1 import cv2

ImportError: libGL.so.1: cannot open shared object file: No such file or directory

状況補足

  • Matplotlibとcv2（OpenCV）を利用
  • Matplotlibの後にOpenCVをインストールした

対処方法

原因

  • MatplotlibとCV2のライブラリの競合（恐らく）
